    Gasket, intake/exhaust manifold

    The Gasket, intake/exhaust manifold (768.112) seals the intake manifold to prevent air and vacuum leaks. Replacing a leaking gasket restores stable engine performance and fuel efficiency.  

    FAQ

    A gasket for an intake or exhaust manifold is a sealing component placed between the manifold and the engine cylinder head. Its function is to create a leak-tight seal, ensuring proper airflow into the engine (intake) and efficient removal of exhaust gases (exhaust), while preventing leaks of air, exhaust gases, or heat.

    Key specifications include shape, port configuration, thickness, and material type. Intake gaskets are often made from rubber, fiber, or composite materials, while exhaust gaskets are typically made from heat-resistant materials such as multi-layer steel or graphite composites. They must withstand high temperatures (especially exhaust gaskets, often exceeding +300°C), pressure, and thermal expansion.

    Replacement is necessary when the gasket is worn, damaged, or leaking. Symptoms of a faulty intake gasket include rough idling, vacuum leaks, or poor performance, while exhaust gasket issues may cause loud exhaust noise, reduced efficiency, or exhaust gas leaks. It is recommended to replace the gasket whenever the manifold is removed.

    Porza offers a fit guarantee option where your vehicle or engine details are checked against product specifications. This ensures the gasket matches the correct shape, port design, and material requirements for your intake or exhaust system.

    Porza supplies high-quality sealing components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This ensures quick access to essential engine parts for both professional workshops and individual users.

    If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a reliable and risk-free purchasing experience.
